Monitoring & Testing Applications

The Water Survey of Canada, a division of Environment Canada, is a federal government agency responsible for collection, interpretation and dissemination of water source data and information.
As a division of Environment Canada, the Water Survey of Canada (WSC) covers a vast range of topographical environs from Arctic Canada to the US border with elevations varying from sea level to over 13,000 feet (4,000 metres). An estimated 7% of the world’s renewable water supplies are found in Canada. Canada’s hydrology is...

The ability to collect useful data about sediment transport and other pollutants closely coupled to SSC (such as nutrients, e-coli, phosphates and nitrates) is dependent on the timing and frequency of manual grab samples during run-off events. Most sediment and pollutant is transported during a small number of storm events which are infrequent and unpredictable. When they do occur, trained personnel or the proper equipment may not be available to collect grab samples. An automated pump sampler can eliminate the...

SUMMARY
Fielded water level measurement stations, based on GaugerGSM sensor, report real time stream levels and flow. Stations are located across a stream-rich region of the upper Galilee feeding the Jordan river in the northern part of Israel. The region is a popular tourist destination due to its biblical origins, rich flora and fauna. Field data is available over the Internet to authorized engineers, site supervisors and Government officials. remote monitoring station - close up

The recorded death of fish in the river that flows out of the industrial zone of Scarlino has created the need of the installation of a biological alarm system. The decision was made to work with an automatic system, iTOXcontrol created by microLAN-The Netherlands represented in Italy by Ecotox Lds, which uses marine bacteria. The system compares the values of the light emission from these organisms at the entrance and exit of the canal, generating alarms in the presence of toxic substances.

We propose our product as a new powerful base for optical absorption analysis. One of the greatest advantages of this method is that virtually any sample in virtually any state may be studied. Liquids, gases, films, powders, surfaces can all be examined with a proper choice of sampling technique. Using LED-PD optopairs for mid-infrared spectral range allows developing portable sensors with high reliability and adequate accuracy that can be successfully applied in different areas for matter analysis purposes.

Subsurface environments are critical not only as water resources but also for energy use including geothermal, CO2 sequestration and oil & gas operations. These sensitive environments are directly affected by anthropogenic activities, hence monitoring is essential. Temperature offers insight into a variety of physical properties and can be used for flow monitoring and flux quantification in the subsurface. Traditionally, point sensors have been used to collect temperature data; however, significant limitations...

Due to green algae problems in the water reservoir of a drinking water treatment plant, the ALGcontrol was installed to continuously monitor the algae concentrations and possible toxic blue green algae blooms. During almost 4 months the ALGcontrol measured the total chlorophyll and cyano chlorophyll concentrations of the water reservoir. In order to be able to compare these results, second off-line controls were carried out using the ISO 10260 chlorophyll-a quantification (extraction into ethanol, spectrophotometri...

The monitoring of Turbidity is key requirement of the water industry in both water supply and water recovery systems. Within the water supply process, monitoring of turbidity allows operators to assess the efficiency of filters for particulate removal through the process. Similarly, with water recovery (Waste Water Treatment Works), the measurement of turbidity is a key parameter to track the removal of particulate through the process. CTG can provide turbidity measurements with the UniLux sensor, or provides...

All construction affects groundwater and a water management plan will be required.
From deforestation to urbanisation, from holes to heaps and dams to drains, they all have an affect on the groundwater.
Deforestation causes an increase in the rate of run off of rainwater resulting in lower percolation of precipitation into the soil and a consequent increase in soil erosion leading to slope instability, hence land and mud slides. The increased rate of run off can cause small streams and large rivers to rise and...

One of the greatest problems facing the planet is the management, conservation and equitable distribution of fresh water supplies. The fresh water sources may be lakes, rivers or ground water aquifers, most of which are now under stress.

Monitor any water quality parameter you collect, no matter where it has been collected from. Store quality data from manually or automatically collected spot samples, and even continuously collected samples such as those from auto-samplers and sondes.

The management of hydro-meteorological data demands the highest process standards. Both recorded and derived data from various observation areas are archived together, edited in graphical and tabular form, analyzed, evaluated and presented. In order that these tasks are carried out efficiently and economically, the support of a specialized software solution is required. Our water data management solutions offer a comprehensive spectrum of functions for integrated collection, processing, quality control, evaluation...

Testing phosphonates in hard water can be difficult due to interference from high levels of calcium. Here we present a phosphonate test method for hard water samples. The method is based on a chemical masking of the calcium.
The WAT hard water phosphonate test uses C30 Spectrophotometer to measure the chromogen PMB and digital thermoreactor to digest the phosphonate compound.
The thermoreactor capacity of 16 simultaneous vials provides for running critical data quality assurance samples.
